Re: [PD] [Pd] Compile external with C++ compiler?
Hi Ed,
Thanks for the advice, although I don't think this piece of work warrants
changing our audio engine :)
ofxPd looks cool though, what's sort of app are you making? (If you can
say).
Cheers,
Joe

Hi Joe,
Have you thought of using ofxPd?
I'm involved in the creation of an app for the iPhone right now, and we're
using ofxPd from Dan Wilcox:
https://github.com/danomatika/ofxPd
Since Openframeworks is a bunch of C++ wrappers for various libraries,
ofxPd adds Pd to the libraries that you can work with in C++.
Then you can call the setup function within the xcode build, and your
object will work in libpd (i.e. ofxPd) in the app environment.
Bear in mind that Apple do not like GnuGPL licensed stuff, so I've created
BSD licensed versions of some of my own Pd externals for this project.
And the app works. We're in the final stages now, so I'll post to the list
when it's complete!
Best,
Ed

*Subject:* [PD] [Pd] Compile external with C++ compiler?
Hi all,
Thought I might as well ask this here because you guys know everything :)
I'm writing an external to be built into an iOS app that's running Pd. The
catch is I need to interface with a C++ library within the external.
The external builds and runs fine if I'm using the C compiler (in Xcode)
but I can't access the C++ library functions. If I switch it to compile in
C++ (by changing the objective-c file from .m to .mm) then I can use the
C++ library functions but it complains that it can't find 'class_addmethod'
*'No matching function for call to
'class_addmethod'*
I've tried declaring the setup function as C code like Katja explains on
her site http://www.katjaas.nl/pitchshift/soundtouch%7E.html:
extern C void external_tilde_setup(void) { }
But that still didn't seem to work. I was also going through the list and
found this
threadhttp://lists.puredata.info/pipermail/pd-list/2002-02/004485.html but
I'm not sure if it's the right approach. Plus I'm more of an audio guy than
programmer :)
Any ideas would be much appreciated.
Thanks,
Joe

Re: [PD] [Pd] Compile external with C++ compiler?
Hi Joe,
It's an app for remixing music. Can't say more than that, but if everything
gets finished on time it will be out next month. Wasn't my idea to make this,
but I've done things like it before. The record label is quite well known...

Re: [PD] dsp processor for PD?
keeping an eye open for this http://sonic-core.net/joomla.soniccore/index.php I still have this 'Creamware Pulsar II' card from the late '90's, but I haven't used it much since I migrated to GNU/Linux. I always imagined it would be very cool to run my patches on it natively though, and now I hear rumours about Open Scope: http://sonic-core.net/joomla.soniccore/index.php?option=com_contentview=articleid=335lang=us http://www.the-new-world-of-music.net/forum/viewtopic.php?f=8t=10sid=0d33ee46cf024f3ee02912249688295a might become interesting? gr, Tim Op 27 april 2012 19:53 schreef Malte Steiner stei...@block4.com het volgende: problem would be PD addressing DSP processors and feed them with tasks.

Re: [PD] [Pd] Compile external with C++ compiler?
It's really easy actually.
You make the object in C, compile it and then build your patch in pd vanilla +
the object.
Then in the xcode object you just call the setup function for the object, the
source code for which gets included in the xcode project.
That's all I know. I'm not responsible for the Xcode/C++ of this app, only the
Pd patch and Pd objects, so there may be more to it. It's quite simple though,
my developer colleague tells me.
Don't forget, C is a subset of C++!

Hi Charles,
Thanks for replying!
I don't believe it's a problem calling C functions, you just have to declare
them with 'extern C' to avoid name mangling (I think??).
The issue is, when I want to use C++ I have to switch the implementation file
to .mm, which is a Objective-C++ file. As soon as I do this Xcode starts
complaining about 'class_addmethod()' in my setup function. The weird thing is
that it only applies to 'class_addmethod()'. For example, 'class_addbang()',
'class_new()' all work fine.
It seems like it's an issue only with this function, and it looks like
class_addMethod is already a function used by Objective-C I think maybe
there's some namespace issues, but I have no idea how to resolve this.
wrote wrapper functions to export a C-callable public interface to C++
functions.
Yep, this is what I'm doing now. A bit annoying because I was so close :)
Thanks for your help!
Cheers,
Joe

Hi guys
The part that I don't get is how to call C functions from C++? I don't
think I've even tried that before. Have you?
Joe: I've built externals that just call C++ functions that I declared
with extern C or wrote wrapper functions to export a C-callable
public interface to C++ functions. Best suggestion I've got is to
identify which functions you've got are going to be public and which
ones are private and plan out how you're going to declare them.
